Large-deformation anti-stamping brownish red 18K gold alloy for jewelry materials and process thereof

Abstract

The invention discloses a large-deformation anti-stamping brownish red 18K gold alloy for jewelry materials and a process thereof. The alloy comprises the following components in percentage, by weight, 0. 3 wt.% to 0. 5wt.% of Ca, 0.2wt.% to 0. 4wt.% of B, 1. 0wt.% to 1.2 wt.% of Re, 1.4 wt.% to 1.8 wt.% of Zr, 5.0 wt.% to 8.0 wt.% of Cu, 10.0 wt.% to 12.0 wt.% of Fe, 74.0 wt.% to 76.0 wt.% of Au,and the balance of silver. According to the method, the current situation that the existing K brownish red gold is insufficient in performance is solved, the development bottleneck in the field of jewelry is effectively broken through, the method has the advantages that the implementation and industrialization of the material can obtain good economic and social benefits.

Description

technical field [0001] The invention relates to the technical field of alloys, in particular to a gold alloy. Background technique [0002] Gold has extremely high stability against corrosion, good electrical and thermal conductivity. Gold also has good craftsmanship and can be easily processed into ultra-thin gold foil, micron gold wire and gold powder. Gold is easily plated on the surface of other metals and pottery and glass, and gold is easily welded and forged under certain pressure. These numerous functional properties make gold or gold alloys widely used in modern high-tech industries, such as electronic technology, communication technology, aerospace technology, chemical technology, medical technology, etc. [0003] The original function of gold was valued as a jewelry and decorative material. With the development of the times and the improvement of people's living standards, people's aesthetic concepts have also been continuously improved, and precious metal jewe...
